4.4 Initial Start Up

4.4.1 Getting Started

Before starting up the system check the following:
1 The dryer has been installed correctly as detailed in this guide.
2 The inlet and outlet ball valves are closed and all covers on the BA-DME are fixed securely in place.
3 A suitable supply of compressed air is available, refer to the technical specification for compressed air requirements.
Note. If a refrigeration dryer has been installed upstream of the adsorption dryer unit the refrigeration dryer must be switched off for at least
one week prior to the start-up of the adsorption dryer unit. After this period the refrigeration dryer can be put back on line. Should the
adsorption dryer unit switch into ecomode earlier than this, the refrigeration dryer can be placed immediately on line again.

4.4.2 Start-Up

All valves must be opened and closed gradually. Pressure peaks will lead to a destruction of the filters and the desiccant.
1 Switch on the electrical supply to the dryer and verify that the yellow "power on" LED on the control panel has illuminated.
2 Slowly open the inlet ball valve until fully open, the adsorption dryer will commence cycling.
3 Verify that there are no leaks within the system.
4 Test the condensate drains of the coalescing filters and verify that they are discharging correctly into a suitable collection vessel.
5 When the dryer is pressurised to full system pressure, slowly open the outlet ball valve.
6 Verify that the column pressure gauges are cycling between zero and full system pressure every three minutes.
7 The dryer will continue to cycle automatically without further intervention.
Note. It will take a period of time for the dryer to reach the specified pressure dewpoint of -40
reached the system is ready for use, and the upstream refrigeration dryer (if fitted) can be placed back on-line.
